Recommandations for Open-Back Headphones

Lately, I've been looking for a pair of nice open-back headphones with some requirements:

Price lower than 200 dollars, even 150 or 100 if possible

Mobile-friendly - I want to use them with my phone and laptop without investing extra money in an amp and dac.

Preferebly over-ear, but comfortable on-ears are fine too.

I'm planning on using them only at home (I have earbuds for commuting) for music, movies, videos and a bit of gaming, and I listen for most genres, but mostly rock (from queen to a7x).

Open back because I did some research, and even though I never tried one, they seem to fit my needs (use at home) and I'd like to try a pair

In my research and came across headphones like the hd598, Grado sr60/80/125e (even though they are on ear), k7xx, dt990s and more, and since I'm new in this subject, I'm very confused (so many headphones).

I have both the Massdrop Sennheiser HD6xx and HiFiman HE4xx. Both can be driven off of a portable, the HD 6xx less so. I would go for the HE4xx because of that. However, to get the best out of them you really do ultimately need an AMP/DAC. I currently use and AudioQuest Dragonfly Black but am eventually going to invest in a desktop AMP/DAC. Just don't know which one yet.
